Anti-aliasing is broken since version 5.3.5 and persists in 5.3.6.1. OpenGL rendering is disabled, the issue is the same regardless of Use anti-aliasing and Use hardware acceleration checkboxes are checked or not.
Windows 7 64-bit, Intel HD 3000 GPU.
None of previous versions had the issue. I would attach screenshots but it is not allowed.
The issue is also present in 5.4.1 version.
